Abstract
The utility model discloses an interlocking device of double isolation switches and a front cabinet door, characterized in that a transmission shaft(4) is arranged between the operation devices(1) of the isolation switches and a front door plate(7), pressure plates(2) are both arranged on the operation devices(1) of the two isolation switches, and a transmission plate(3) and an interlocking plate (5) are fixed at the two ends of the transmission shaft(4) respectively; the transmission plate(3) and the pressure plates(2) form linkage, the interlocking plate (5) and a door plate hook(8) form interlocking, and a reset extension spring(6) is arranged between the interlocking plate (5) and a fixing plate(9).
Description
Technical field
The utility model relates to a kind of switch with double-isolation of electrical power distribution system and Qianmen cabinet door interlock.
Background technology
In the power transmission and distribution system, the work about electric power personnel have proposed very high requirement to the fail safe of equipment for power transmission and distribution, and particularly fixed switch cubicle is definitely can not open the Qianmen under charged situation.At present, usually can run in engineering contract that two isolating switches are used for two different distribution loops in a switch cubicle,, require to have no linkage relationship between two isolating switches in order to satisfy the distribution needs.In this case, two conventional chain just not having of isolating switch and Qianmen should have protective effect, usually can make maintainer's mistakenly entering charged chamber.At this moment, just need a kind of can the assurance not have linkage relationship between two isolating switches, can guarantee to have only two isolating switches to be in the interlock that gate-dividing state just can be opened the Qianmen simultaneously again.
The utility model content
The purpose of the utility model is designed a kind of can the assurance does not exactly have linkage relationship between two isolating switches, satisfies the needs of distribution loop, can guarantee to have only two isolating switches to be in the interlock that gate-dividing state just can be opened the Qianmen simultaneously again.
The technical scheme that the utility model adopts is: a kind of switch with double-isolation and Qianmen cabinet door interlock; It is characterized in that; A connecting rod transmission controlling mechanism is set between two isolating switches and front door of switch cabinet, makes two isolating switches become interlocking with front door of switch cabinet simultaneously through pressing plate, transmission pressing plate, power transmission shaft, junction panel, extension spring and door-plate hook.
After isolating switch closed a floodgate, the swing offset of isolator operating mechanism was linked up with door-plate through the transmission of pressing plate, transmission pressing plate, power transmission shaft, junction panel locked, and the Qianmen of switch cubicle can't be opened, and extension spring is simultaneously drawn back.Behind two equal separating brakes of isolating switch, the swing offset of isolator operating mechanism makes pressing plate separate with the transmission pressing plate, and at this moment chain pressing plate separates with the door-plate hook under the drive of extension spring, and front door of switch cabinet just can be opened.
Description of drawings
Fig. 1 faces structural representation for the utility model switch with double-isolation and Qianmen cabinet door interlock embodiment when isolator operating mechanism is threaded to "on" position;
Fig. 2 is the left TV structure sketch map when isolator operating mechanism is threaded to "on" position embodiment illustrated in fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: 1, isolator operation device 2, pressing plate 3, driver plate 4, power transmission shaft 5, junction panel 6, extension spring 7, front door 8, door-plate are linked up with 9 fixed heads
Shown in accompanying drawing; The utility model switch with double-isolation and Qianmen cabinet door interlock are between isolator operation device 1 and front door 7, to be provided with a power transmission shaft 4; Be equipped with pressing plate 2 on the operating means 1 of two isolating switches, power transmission shaft 4 two ends are fixed with driver plate 3 and junction panel 5 respectively, and driver plate 3 forms interlock with pressing plate 2; Junction panel 5 is chain with 8 formation of door-plate hook, between fixed head 9, is provided with reset tension spring 6 at junction panel 5.
After isolating switch closes a floodgate; The rotation of isolator operation device 1 makes pressing plate 2 produce a swing offset simultaneously; Pressing plate 2 drives driver plates 3 to be turned clockwise power transmission shaft 4, junction panel 5 door-plate is linked up with 8 locked, and the Qianmen 7 of switch cubicle can't be opened, and extension spring is simultaneously drawn back.Behind two equal separating brakes of isolating switch, the swing offset of isolator operation device 1 makes pressing plate 2 separate with transmission pressing plate 3, and at this moment chain pressing plate 8 separates with door-plate hook 8 under the drive of extension spring 6, and front door of switch cabinet 7 just can be opened.
The cabinet door interlock that the utility model provides is made simple and easy, easy for installation, simple to operate, and interlocking is reliable, can satisfy the requirement of work about electric power personnel to the equipment for power transmission and distribution fail safe.
